McKinney, TX (Feb 22, 2018) – Developing Solutions, Inc. has added the SWu interface application to its dsTest suite of network testing applications.   dsTest supports additional VoWiFi/VoWLAN testing with the SWu interface.

SWu is an Internet Key Exchange version 2 (IKEv2)-based interface, used to perform authentication, session creation, and negotiate  IP Security (IPSec) sessions used at the user plane level.  IKEv2 is the protocol used to set up  security associations (SA) in the IPsec protocol suite.

IPSec tunnels are established from the User Equipment (UE) and the evolved Packet Data Gateway (ePDG), allowing access to the Evolved Packet Core (EPC) from non-3GPP untrusted networks.  The UE establishes separate SWu instances for each PDN connection, and transports the packets of all bearers for the same PDN Connection between the UE and the ePDG.

About dsTest

Developing Solutions’ growing collection of protocol applications and Subscriber Management, Policy and Charging Control, EPC, IMS/VoLTE, CIoT/NB-IoT, eMBMS, SMS, VoWiFi and WLAN Interworking testing tools gives dsTest the ability to identify problems and potential bottlenecks in the lab before they show up in the network.

In addition to Control Plane interfaces, dsTest also support User Data interfaces.

dsTest runs on several distributions of Linux and is designed to take advantage of the latest processor and virtualization technology available with COTS hardware in order to provide high performance and capacity, and assists carriers and vendors in their drive toward network function virtualization (NFV) and software defined networks (SDN).  Wireless Service Providers and Network Equipment Manufacturers rely on dsTest to for performance, compliance, and reliability validation of their network devices and architectures.  dsTest is accompanied by the dsClient graphic user interface (GUI), which allows easy configuration and control of the tool, and provides live operational measurements monitoring in chart or tabular form.

dsTest further simplifies the process of testing the signaling core with multiple advanced testing features and solutions, such as C-SGN, SmartEvents, Diameter Dictionary validation, and SmartAVP.
